'Hopping' in the IDE?

I have seen something like this sporadically as well. I think it comes more with "if" statements though. As you say, they are harmless but confusing. I have no reliable handlers that would demonstrate the effect.

Subject: 'Hopping' in the IDE?


I'm seeing something a bit strange while tracing the running of scripts in the 
IDE (I'm using LC 6.5.1 on a Mac with Mavericks). What I find is that as I watch 
the activation step through statements, there are lines that invoke other 
handlers, and as is normal, if I don't choose the 'step over' option, I see 
control pass to one of these handlers and then eventually return to the main 
stream of the script. 

So far so good: but I find that sometimes when I step into a statement that 
doesn't call a subsidiary handler - one example is a statement as simple as

 replace "A" with "B" in myVariable

Then the IDE hops to a subsidiary and shows control passing to the initial 'on' 
statement of that handler and then moving back to the main script, without the 
script of the subsidiary being executed. So this change of attention of the IDE 
seems like a kind of false trail, which is harmless but confusing.

This is very odd but it's also rather elusive. I am still struggling to get a 
repeatable example, but it looks like a bug from here. Has anyone else seen 
anything like this?

TIA

Graham
